How to Improve FPS in Unreal Engine Virtual Production ?

Achieving high FPS (frames per second) is crucial in Unreal Engine virtual production to ensure smooth real-time rendering. A low frame rate can cause lag, stuttering, and performance issues, impacting the quality of your virtual production. In this guide, we’ll explore various optimization techniques to enhance FPS in Unreal Engine.

1. Optimize Scene and Assets

  • Use Level of Detail (LOD): Implement LODs for models to reduce polygon count when viewed from a distance.

  • Reduce Polycount: Optimize high-poly assets using tools like Simplygon or Unreal Engine’s built-in LOD tools.

  • Use Nanite (UE5): Nanite allows for high-detail models with better performance, eliminating the need for manual LODs.

2. Optimize Lighting and Shadows

  • Use Static and Baked Lighting: Instead of dynamic lights, bake lighting where possible to reduce GPU load.

  • Limit Dynamic Shadows: Use fewer real-time shadows and adjust shadow resolution to a lower setting.

  • Use Distance Field Shadows: They are more optimized for large environments compared to traditional shadow maps.

  • Disable Unused Lights: Keep only essential real-time lights enabled.



3. Optimize Materials and Textures

  • Use Efficient Materials: Avoid complex shader calculations and use material instances for optimization.

  • Reduce Texture Resolution: Use compressed and mipmapped textures (e.g., 1K or 2K instead of 4K+).

  • Enable Virtual Texturing: Helps reduce memory usage and improves performance.

4. Adjust Rendering Settings for Performance

  • Lower Screen Percentage: Reduce rendering resolution under Settings > Engine Scalability.

  • Optimize Anti-Aliasing: Use FXAA or TAA instead of heavier MSAA.

  • Disable Ray Tracing (if unnecessary): Ray tracing significantly impacts performance, so disable it if not required.

  • Use Temporal Super Resolution (TSR) in UE5: Provides better upscaling with improved performance.

5. Optimize Blueprint and Code Performance

  • Reduce Tick Rate in Blueprints: Avoid running expensive calculations every frame.

  • Use Event-Driven Logic: Instead of running continuous loops, use event-driven functions where possible.

  • Profile Performance: Use Unreal’s Profiler to find performance bottlenecks.

6. Use Efficient Virtual Production Techniques

  • Optimize Camera Settings: Reduce render resolution and enable motion blur efficiently.

  • Use GPU Lightmass: Helps in pre-baking lighting for virtual production setups.

  • Streamline Chroma Keying: In Aximmetry or other external tools, optimize green screen settings to reduce GPU load.

7. Hardware Optimization

  • Use a High-End GPU: Virtual production relies heavily on the GPU, so a powerful RTX-series or equivalent is recommended.

  • Increase RAM Capacity: More RAM allows Unreal Engine to handle large assets smoothly.

  • Use SSD Storage: Faster asset loading improves scene rendering speeds.
